Hi everyone, this is my first post here. I'm offered to by Sunn Coliseum 300 head with Marshall JCM800 bass cab consisting of 4 Celestion G12-65. Any idea how will this two pair? Sunn amp strength is: 300 WRMS @ 2 ohms 200 WRMS @ 4 ohms 120 WRMS @ 8 ohms Each cone in cab is labeled as 15 ohms, though I think it's actually 16 ohms. Also does anyone have opinion on this cab and amp? Thanks.
